Description

Technical Field

[0001] This invention relates to the field of ore crushing technology, and in particular to a mining crushing device with dust collection function. Background Technology

[0002] Mining crushing equipment is a type of mechanical equipment used for crushing ores, minerals, rocks, and other materials. It is widely used in mining, metallurgy, building materials, highway, and railway industries, in primary or secondary crushing processes. Its main purpose is to mechanically crush ores or other materials into smaller particle sizes to facilitate subsequent processing and extraction. Depending on their working principle and application, mining crushing equipment comes in various types, such as jaw crushers, impact crushers, cone crushers, hammer crushers, and roller crushers. Jaw crushers, in particular, use the relative movement of two jaw plates to apply compressive force to the ore, thus crushing the material. Jaw crushers are generally used for primary ore crushing, possessing high crushing capacity, simple structure, and convenient operation and maintenance. They are suitable for ores of various hardnesses, have stable start-up and operation, and can withstand large loads. However, existing mining crushing equipment typically generates a large amount of dust during ore crushing, causing environmental pollution and posing health hazards to nearby workers. Therefore, efficient dust collection is necessary to mitigate these hazards. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: a mining crushing device with dust collection function, comprising a crushing device, the crushing device including a crushing box, the crushing device being used to crush ore, a dust removal device being provided on the crushing device, the dust removal device including a soot blowing cylinder, the soot blowing cylinder being fixedly installed with the crushing box, a dust collection device being provided on the dust removal device, the dust collection device including a collection box, the dust removal device and the dust collection device being used to collect dust generated during ore crushing; The crushing device includes a set of upper connecting rods and a set of lower connecting rods symmetrically rotatably mounted on the inner wall of the crushing box. An upper jaw plate is rotatably mounted on the upper connecting rods. Two eccentric wheels are rotatably mounted on the crushing box. The upper jaw plate is eccentrically rotatably mounted with the upper eccentric wheel. A lower jaw plate is rotatably mounted on the lower connecting rods. The lower jaw plate is eccentrically rotatably mounted with the lower eccentric wheel. An upper crushing plate and a lower crushing plate are slidably mounted inside the crushing box. Two adjusting mechanisms are provided on the crushing box. The adjusting mechanisms are used to adjust the positions of the upper crushing plate and the lower crushing plate. The dust removal device includes a feed plate fixedly installed at the bottom of the dust blowing cylinder. The feed plate is fixedly installed with the collection box. A central shaft is rotatably installed on the feed plate. A stone-throwing disc is fixedly installed on the central shaft. Several blades are provided on the stone-throwing disc. The upper surface of the stone-throwing disc is conical. The dust collection device includes a dust collection box fixedly installed on the side of the collection box, an exhaust fan fixedly installed on the dust collection box, six suction fans fixedly installed on the side of the collection box, an inner filter screen and an outer filter plate fixedly installed on the side of the dust collection box, and a cleaning mechanism for cleaning the outer filter plate is provided on the dust collection box.

[0004] Furthermore, the crushing device also includes a crushing motor fixedly installed on the crushing box. A motor bevel gear is fixedly installed on the motor shaft of the crushing motor. A docking shaft is rotatably installed on the side of the crushing box. A docking bevel gear and two drive wheels are fixedly installed on the docking shaft. An upper transmission wheel is fixedly installed on the upper eccentric wheel, and a lower transmission wheel is fixedly installed on the lower eccentric wheel. An upper transmission belt is wound around the upper transmission wheel and the drive wheel, and a lower transmission belt is wound around the upper transmission wheel and the lower transmission wheel.

[0005] Furthermore, the adjustment mechanism also includes an adjustment electric cylinder rotatably mounted on the side of the crushing box. A rotating groove rod is rotatably mounted on the side of the crushing box. The rotating groove rod is rotatably mounted with the output end of the adjustment electric cylinder. Two symmetrical sliding grooves are provided on the rotating groove rod. Sliding rods are fixedly mounted on both the upper and lower crushing plates. Rotating sleeves are rotatably mounted on the sliding rods. The two rotating sleeves slide in the two sliding grooves of the rotating groove rod, respectively.

[0006] The rotation of the crushing motor drives the motor bevel gear to rotate, which in turn drives the docking shaft and drive wheel to rotate. The upper drive belt drives the upper drive wheel to rotate, and the lower drive belt drives the lower drive wheel to rotate. The upper and lower drive wheels drive two eccentric wheels to rotate, which in turn drive the upper and lower jaw plates to rotate eccentrically. Under the action of the upper and lower connecting rods, the upper and lower jaw plates oscillate continuously.

[0007] The ore to be crushed is placed from the top of the crushing box. The ore first reaches between the upper crushing plate and the upper jaw plate. The ore is initially crushed by the back-and-forth swing of the upper jaw plate. Then the ore reaches between the lower jaw plate and the lower crushing plate. The ore is further crushed by the swing of the lower jaw plate and the lower crushing plate. After crushing, the ore falls into the soot blowing tube.

[0008] Adjusting the extension and retraction of the electric cylinder drives the rotating groove rod to rotate around the crushing box. This, in turn, drives the two sliding rods to move inward or outward simultaneously through the sliding groove and rotating sleeve on the rotating groove rod. This, in turn, drives the upper crushing plate and the lower crushing plate to move inward or outward simultaneously, thus adjusting the position of the upper crushing plate and the lower crushing plate.

[0009] Furthermore, the side of the soot blowing cylinder is provided with several ash outlet holes, through which dust can pass. A dust extraction ring is fixedly installed on the outside of the soot blowing cylinder, located outside the ash outlet holes. An ash inlet pipe is fixedly installed on the outside of the dust extraction ring, and the ash inlet pipe is fixedly installed with the dust collection box. A lower bevel gear and a fan blade are fixedly installed on the central shaft. An isolation cylinder is fixedly installed on the feed plate, and a connecting frame is fixedly installed inside the isolation cylinder. The central shaft and the connecting frame are rotatably installed. Several ventilation grooves are provided on the isolation cylinder.

[0010] Furthermore, two extension rods are fixedly installed on the central shaft, and scrapers are fixedly installed on the extension rods, with the scrapers fitting against the outer wall of the insulating cylinder.

[0011] The crushed ore falls onto the throwing disc. The rotation of the central shaft drives the fan blades and the throwing disc to rotate. The fan blades blow air outward through the ventilation slots of the isolation cylinder. The ore on the throwing disc slides through the conical inclined surface of the throwing disc between the blowing cylinder and the isolation cylinder. The rotation of the throwing disc provides centrifugal force, which, together with the blowing air from the fan blades, throws the dust generated by the crushing of the ore into the ash outlet. The dust enters the ash extraction ring through the ash outlet and is eventually extracted by the fan through the ash inlet pipe. The rotation of the central shaft also drives the scraper to move through the extended rod. The scraper pushes the ore located between the blowing cylinder and the isolation cylinder into the drop pipe.

[0012] Furthermore, the dust collection device also includes a discharge slope fixedly installed on the side of the collection box, a bottom motor fixedly installed at the bottom of the feed plate, a motor gear fixedly installed on the motor shaft of the bottom motor, the motor gear meshing with the lower bevel gear, an inner bevel gear rotatably installed at the bottom of the feed plate, an outer bevel gear fixedly installed on the inner bevel gear, the inner bevel gear meshing with the lower bevel gear, a gear shaft rotatably installed at the bottom of the feed plate, a mating gear and two drive wheels fixedly installed on the gear shaft, the mating gear meshing with the outer bevel gear.

[0013] Furthermore, two conveyor wheels are rotatably installed inside the collection box. A driven wheel is fixedly installed on the conveyor wheel near the inner filter screen. An inclined transmission belt is wound around the driven wheel and the driving wheel. A conveyor belt is wound around the two conveyor wheels. Several push plates are provided on the conveyor belt. A drop pipe is provided at the bottom of the feed plate.

[0014] Furthermore, the cleaning mechanism includes a cleaning motor fixedly installed on the side of the dust collection box, an output gear fixedly installed on the motor shaft of the cleaning motor, two bidirectional lead screws rotatably installed inside the dust collection box, lead screw wheels fixedly installed on the bidirectional lead screws, a transmission gear fixedly installed on the lead screw wheel near the cleaning motor, the transmission gear meshing with the output gear, a transmission belt wrapped around the two lead screw wheels, and two tensioning wheels rotatably installed on the dust collection box, the tensioning wheels being used to tension the transmission belt.

[0015] Furthermore, a fixed rack is fixedly installed inside the dust collection box, and an internal threaded sleeve is rotatably installed on the bidirectional lead screw through a thread. The internal threaded sleeve and the bidirectional lead screw form a threaded transmission. A cleaning wheel is rotatably installed on the internal threaded sleeve, and a cleaning gear is fixedly installed on the cleaning wheel. The cleaning gear meshes with the fixed rack.

[0016] After initial dust removal, the ore falls onto the conveyor belt through the drop pipe. The suction fan blows air into the collection box, and the extraction fan draws the dust out of the collection box and dust collection box. The dust in the ash inlet pipe is drawn onto the outer filter plate, which only allows air to pass through. The dust drawn from the ash inlet pipe falls from below the dust collection box. At the same time, the extraction fan draws the dust remaining on the ore that has fallen onto the drop pipe and conveyor belt onto the outer filter plate. Subsequently, the dust falls from below the dust collection box. The inner filter screen is used to block the ore. The bottom motor rotates, which drives the motor gear to rotate, thereby driving the lower bevel gear and the central shaft to rotate, which in turn drives the inner bevel gear and the outer bevel gear to rotate, driving the mating gear, gear shaft and driving wheel to rotate. Through the inclined transmission belt, the driven wheel and the conveyor wheel are driven to rotate. The dust-removed ore is transported to the discharge slope through the conveyor belt and push plate, and the ore falls out from the discharge slope.

[0017] As usage time increases, dust may accumulate on the outer filter plate, causing it to become clogged and affecting dust collection. The cleaning motor rotates, driving the output gear, which in turn drives the transmission gear and lead screw wheel. This drives another lead screw wheel via a transmission belt, causing both double-acting lead screws to rotate simultaneously. This causes the inner threaded sleeve to slide up and down, which in turn causes the sweeping wheel to slide up and down. Simultaneously, the sweeping wheel drives the sweeping gear to move together. Under the action of the fixed rack, the sweeping wheel and sweeping gear rotate relative to the inner threaded sleeve, thus achieving simultaneous lifting and rotating of the sweeping wheel. The sweeping wheel cleans the surface of the outer filter plate, brushing off the dust adhering to the outer filter plate and discharging it from the bottom of the dust collection box.

[0018] The beneficial effects of this invention compared with the prior art are: (1) The crushing device set in this invention performs double crushing of the ore through two sets of crushing jaw plates. At the same time, the distance between the upper crushing plate and the lower crushing plate can be adjusted according to different needs. At the same time, the two sets of crushing jaw plates can work simultaneously through a power source, resulting in good crushing effect; (2) The dust removal device set in this invention can absorb the dust generated after the ore is crushed, so that the dust is separated from the ore, achieving the initial removal of dust. Then, the dust collection device further removes and collects the dust remaining on the ore, resulting in good dust removal and collection effect; (3) The dust removal device and the dust collection device set in this invention are driven by the same power source, realizing the coordinated operation of the crushed ore movement, the separation of ore and dust, and the automatic discharge of ore. The degree of automation is high and the continuity is good; (4) The cleaning mechanism set in this invention can fully clean the external filter plate, preventing the external filter plate from becoming clogged after the device has been used for a period of time, which would lead to a decrease in the dust collection effect.

A dust collection device is provided on the dust removal device. The dust collection device includes a collection box 301. The dust removal device and the dust collection device are used to collect the dust generated during ore crushing. The crushing device includes a set of upper connecting rods 119 and a set of lower connecting rods 120 symmetrically rotatably mounted on the inner wall of the crushing box 101. An upper jaw plate 115 is rotatably mounted on the upper connecting rod 119. Two eccentric wheels 121 are rotatably mounted on the crushing box 101.

The dust removal device includes a feed plate 202 fixedly installed at the bottom of the soot blowing cylinder 201. The feed plate 202 is fixedly installed with the collection box 301. A central shaft 208 is rotatably installed on the feed plate 202. A stone-throwing disc 206 is fixedly installed on the central shaft 208. Several blades are provided on the stone-throwing disc 206. The upper surface of the stone-throwing disc 206 is conical. The dust collection device includes a dust collection box 302 fixedly installed on the side of the collection box 301, an exhaust fan 319 fixedly installed on the dust collection box 302, six suction fans 303 fixedly installed on the side of the collection box 301, an inner filter screen 318 and an outer filter plate 331 fixedly installed on the side of the dust collection box 302, and a cleaning mechanism for cleaning the outer filter plate 331 is provided on the dust collection box 302.

[0032] like Figure 2 , Figure 3 As shown, the crushing device also includes a crushing motor 102 fixedly installed on the crushing box 101. A motor bevel gear 103 is fixedly installed on the motor shaft of the crushing motor 102. A docking shaft 104 is rotatably installed on the side of the crushing box 101. A docking bevel gear 105 and two drive wheels 106 are fixedly installed on the docking shaft 104. An upper transmission wheel 108 is fixedly installed on the upper eccentric wheel 121, and a lower transmission wheel 110 is fixedly installed on the lower eccentric wheel 121. An upper transmission belt 107 is wound around the upper transmission wheel 108 and the drive wheel 106, and a lower transmission belt 109 is wound around the upper transmission wheel 108 and the lower transmission wheel 110.

[0033] like Figure 2 , Figure 3 As shown, the adjustment mechanism also includes an adjustment electric cylinder 111 rotatably mounted on the crushing box 101. A rotating groove rod 114 is rotatably mounted on the crushing box 101. The rotating groove rod 114 is rotatably mounted to the output end of the adjustment electric cylinder 111. Two symmetrical sliding grooves are provided on the rotating groove rod 114. Sliding rods 112 are fixedly mounted on both the upper crushing plate 116 and the lower crushing plate 118. Rotating sleeves 113 are rotatably mounted on the sliding rods 112. The two rotating sleeves 113 slide in the two sliding grooves of the rotating groove rod 114 respectively.

[0034] The rotation of the crushing motor 102 drives the motor bevel gear 103 to rotate, which in turn drives the docking shaft 104 and the drive wheel 106 to rotate via the docking bevel gear 105. The upper drive belt 107 drives the upper drive wheel 108 to rotate, and the lower drive belt 109 drives the lower drive wheel 110 to rotate. The upper drive wheel 108 and the lower drive wheel 110 drive the two eccentric wheels 121 to rotate, which in turn drives the upper jaw plate 115 and the lower jaw plate 117 to rotate eccentrically. Under the action of the upper connecting rod 119 and the lower connecting rod 120, the upper jaw plate 115 and the lower jaw plate 117 oscillate continuously.

[0035] The ore to be crushed is placed from above the crushing box 101. The ore first reaches between the upper crushing plate 116 and the upper jaw plate 115. The ore is initially crushed by the back-and-forth swing of the upper jaw plate 115 in conjunction with the upper crushing plate 116. Then the ore reaches between the lower jaw plate 117 and the lower crushing plate 118. The ore is further crushed by the swing of the lower jaw plate 117 in conjunction with the lower crushing plate 118. After crushing, the ore falls into the soot blowing cylinder 201.

[0036] The extension and retraction of the electric cylinder 111 drives the rotating groove rod 114 to rotate around the crushing box 101. This causes the two sliding rods 112 to move inward or outward simultaneously through the sliding groove and rotating sleeve 113 on the rotating groove rod 114. This, in turn, causes the upper crushing plate 116 and the lower crushing plate 118 to move inward or outward simultaneously, thus adjusting the position of the upper crushing plate 116 and the lower crushing plate 118.

[0037] like Figures 4-6 As shown, the side of the soot blowing cylinder 201 is provided with several ash outlet holes 207, through which dust can pass. A dust extraction ring 203 is fixedly installed on the outside of the soot blowing cylinder 201. The dust extraction ring 203 is located outside the ash outlet holes 207. An ash inlet pipe 204 is fixedly installed on the outside of the dust extraction ring 203. The ash inlet pipe 204 is fixedly installed with the dust collection box 302. A lower bevel gear 209 and a fan blade 210 are fixedly installed on the central shaft 208. An isolation cylinder 205 is fixedly installed on the feed plate 202. A connecting frame 211 is fixedly installed inside the isolation cylinder 205. The central shaft 208 and the connecting frame 211 are rotatably installed. Several ventilation slots are provided on the isolation cylinder 205.

[0038] like Figures 4-6 As shown, two extension rods 212 are fixedly installed on the central shaft 208, and scrapers 213 are fixedly installed on the extension rods 212. The scrapers 213 are in contact with the outer wall of the isolation cylinder 205.

[0039] The crushed ore falls onto the throwing disc 206. The rotation of the central shaft 208 drives the fan blades 210 and the throwing disc 206 to rotate. The fan blades 210 blow air outward through the ventilation slots of the isolation cylinder 205. The ore on the throwing disc 206 slides through the conical inclined surface of the throwing disc 206 to the space between the blowing cylinder 201 and the isolation cylinder 205. The rotation of the throwing disc 206 provides centrifugal force and, together with the blowing air from the fan blades 210, throws the dust generated by the crushing of the ore into the ash outlet 207. The dust enters the ash extraction ring 203 through the ash outlet 207 and is finally extracted by the fan 319 through the ash inlet pipe 204. The rotation of the central shaft 208 also drives the scraper 213 to move through the extension rod 212. The scraper 213 pushes the ore located between the blowing cylinder 201 and the isolation cylinder 205 into the drop pipe 304.

[0040] like Figures 7-10 As shown, the dust collection device also includes a discharge slope 305 fixedly installed on the side of the collection box 301. A bottom motor 309 is fixedly installed at the bottom of the feed plate 202. A motor gear 310 is fixedly installed on the motor shaft of the bottom motor 309. The motor gear 310 meshes with the lower bevel gear 209. An inner bevel gear 311 is rotatably installed at the bottom of the feed plate 202. An outer bevel gear 312 is fixedly installed on the inner bevel gear 311. The inner bevel gear 311 meshes with the lower bevel gear 209. A gear shaft 313 is rotatably installed at the bottom of the feed plate 202. A mating gear 314 and two drive wheels 315 are fixedly installed on the gear shaft 313. The mating gear 314 meshes with the outer bevel gear 312.

[0041] like Figures 7-10 As shown, two conveyor wheels 306 are rotatably installed inside the collection box 301. A driven wheel 317 is fixedly installed on the conveyor wheel 306 near the inner filter screen 318. An inclined transmission belt 316 is wound around the driven wheel 317 and the driving wheel 315. A conveyor belt 307 is wound around the two conveyor wheels 306. Several push plates 308 are provided on the conveyor belt 307. A drop pipe 304 is provided at the bottom of the feed plate 202.

[0042] like Figures 7-10 As shown, the cleaning mechanism includes a cleaning motor 320 fixedly installed on the side of the dust collection box 302. An output gear 321 is fixedly installed on the motor shaft of the cleaning motor 320. Two bidirectional lead screws 326 are rotatably installed inside the dust collection box 302. A lead screw wheel 323 is fixedly installed on the bidirectional lead screw 326. A transmission gear 322 is fixedly installed on the lead screw wheel 323 near the cleaning motor 320. The transmission gear 322 meshes with the output gear 321. A transmission belt 325 is wound around the two lead screw wheels 323. Two tensioning wheels 324 are rotatably installed on the dust collection box 302. The tensioning wheels 324 are used to tension the transmission belt 325.

[0043] like Figures 7-10As shown, a fixed rack 327 is fixedly installed inside the dust collection box 302. An internal threaded sleeve 330 is rotatably installed on the bidirectional lead screw 326 via a thread. The internal threaded sleeve 330 and the bidirectional lead screw 326 form a threaded transmission. A sweeping wheel 328 is rotatably installed on the internal threaded sleeve 330. A sweeping gear 329 is fixedly installed on the sweeping wheel 328. The sweeping gear 329 meshes with the fixed rack 327.

[0044] After preliminary dust removal, the ore falls through drop pipe 304 onto conveyor belt 307. Intake fan 303 blows air into collection box 301, and extraction fan 319 draws dust out of collection box 301 and dust collection box 302. Dust in inlet pipe 204 is drawn onto outer filter plate 331, which only allows air to pass through. Dust drawn from inlet pipe 204 falls from below dust collection box 302. Simultaneously, extraction fan 319 draws residual dust from the ore that has fallen onto drop pipe 304 and conveyor belt 307 onto outer filter plate 331. Subsequently, the dust falls from the dust collection box 302. The dust falls from below the dust box 302. The inner filter screen 318 is used to block the ore. The bottom motor 309 rotates, which drives the motor gear 310 to rotate, thereby driving the lower bevel gear 209 and the central shaft 208 to rotate, which in turn drives the inner bevel gear 311 and the outer bevel gear 312 to rotate, which drives the mating gear 314, the gear shaft 313 and the driving wheel 315 to rotate. Through the inclined transmission belt 316, the driven wheel 317 and the conveyor wheel 306 rotate. Through the conveyor belt 307 and the push plate 308, the dust-removed ore is transported to the discharge slope 305, and the ore falls out from the discharge slope 305.

[0045] As usage time increases, dust may remain on the outer filter plate 331, causing it to become clogged and affecting dust collection. The cleaning motor 320 rotates, driving the output gear 321 to rotate, which in turn drives the transmission gear 322 and the lead screw wheel 323 to rotate. Through the transmission belt 325, another lead screw wheel 323 rotates, which in turn drives the two bidirectional lead screws 326 to rotate simultaneously. This causes the inner threaded sleeve 330 to slide up and down, which in turn causes the sweeping wheel 328 to slide up and down. At the same time, the sweeping wheel 328 drives the sweeping gear 329 to move together. Under the action of the fixed rack 327, the sweeping wheel 328 and the sweeping gear 329 rotate relative to the inner threaded sleeve 330, thus realizing that the sweeping wheel 328 rotates while rising and falling. The sweeping wheel 328 cleans the surface of the outer filter plate 331, brushing off the dust attached to the outer filter plate 331 and discharging it from the bottom of the dust collection box 302.

[0046] The working principle of the mining crushing device with dust collection function disclosed in this invention is as follows: the extension and retraction of the electric cylinder 111 drives the rotating groove rod 114 to rotate around the crushing box 101, thereby driving the two sliding rods 112 to move inward or outward simultaneously through the sliding groove and rotating sleeve 113 on the rotating groove rod 114, thereby driving the upper crushing plate 116 and the lower crushing plate 118 to move inward or outward simultaneously, and adjusting the position of the upper crushing plate 116 and the lower crushing plate 118. The rotation of the crushing motor 102 drives the motor bevel gear 103 to rotate, which in turn drives the docking shaft 104 and the drive wheel 106 to rotate via the docking bevel gear 105. The upper drive belt 107 drives the upper drive wheel 108 to rotate, and the lower drive belt 109 drives the lower drive wheel 110 to rotate. The upper drive wheel 108 and the lower drive wheel 110 drive the two eccentric wheels 121 to rotate, which in turn drives the upper jaw plate 115 and the lower jaw plate 117 to rotate eccentrically. Under the action of the upper connecting rod 119 and the lower connecting rod 120, the upper jaw plate 115 and the lower jaw plate 117 oscillate continuously. The ore to be crushed is placed from above the crushing box 101. The ore first reaches between the upper crushing plate 116 and the upper jaw plate 115. The ore is initially crushed by the back-and-forth swing of the upper jaw plate 115 in conjunction with the upper crushing plate 116. Then the ore reaches between the lower jaw plate 117 and the lower crushing plate 118. The ore is further crushed by the swing of the lower jaw plate 117 in conjunction with the lower crushing plate 118. After crushing, the ore falls into the soot blowing cylinder 201. The crushed ore falls onto the throwing disc 206. The rotation of the central shaft 208 drives the fan blades 210 and the throwing disc 206 to rotate. The fan blades 210 blow air outward through the ventilation slots of the isolation cylinder 205. The ore on the throwing disc 206 slides through the conical inclined surface of the throwing disc 206 to the space between the blowing cylinder 201 and the isolation cylinder 205. The rotation of the throwing disc 206 provides centrifugal force and, together with the blowing air from the fan blades 210, throws the dust generated by the crushing of the ore into the ash outlet 207. The dust enters the ash extraction ring 203 through the ash outlet 207 and is finally extracted by the fan 319 through the ash inlet pipe 204. The rotation of the central shaft 208 also drives the scraper 213 to move through the extension rod 212. The scraper 213 pushes the ore located between the blowing cylinder 201 and the isolation cylinder 205 into the drop pipe 304.After preliminary dust removal, the ore falls through drop pipe 304 onto conveyor belt 307. Intake fan 303 blows air into collection box 301, and extraction fan 319 draws dust out of collection box 301 and dust collection box 302. Dust in inlet pipe 204 is drawn onto outer filter plate 331, which only allows air to pass through. Dust drawn from inlet pipe 204 falls from below dust collection box 302. Simultaneously, extraction fan 319 draws residual dust from the ore that has fallen onto drop pipe 304 and conveyor belt 307 onto outer filter plate 331. Subsequently, the dust falls from the dust collection box 302. The dust falls from below the dust box 302. The inner filter screen 318 is used to block the ore. The bottom motor 309 rotates, which drives the motor gear 310 to rotate, thereby driving the lower bevel gear 209 and the central shaft 208 to rotate, which in turn drives the inner bevel gear 311 and the outer bevel gear 312 to rotate, which drives the mating gear 314, the gear shaft 313 and the driving wheel 315 to rotate. Through the inclined transmission belt 316, the driven wheel 317 and the conveyor wheel 306 rotate. Through the conveyor belt 307 and the push plate 308, the dust-removed ore is transported to the discharge slope 305, and the ore falls out from the discharge slope 305.
